IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 209,673, dated November5, 1878; application filed October 15, 1878.

To all whom it may concern:

Be it known that 1, JOHN M. GRILLEN BERGER, of the city of Syracuse, inthe county of Onondaga, in the State of New York, have invented new anduseful Improvements in Pumps, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

Figure l is an exterior view of my invention; Fig. 2, a vertical sectionof same; Fig. 3, a side view of the standard which supports the upperextremity of the discharge-pipe, and the means by which the pump isoperated, and Fig. 4 illustrates modifications in some of the details ofmy invention.

Similar letters of reference indicate corresponding parts. e

A A represent two cylinders, preferably of hard-burnt or vitrifiedpotters clay, and arranged side by side. They are open at both ends, andupon the top of them is fitted a plate, a, provided with a port for eachcylinder. Upon the top of this plate is secured a sheet of rubber orleather, extending to the outer edges of said plate, to form a packingfor the joint between it and the cap amounted on top thereof. Over theports in the plate a are formed valves in the usual manner-viz, bymaking in the rubber or leather sheet aforesaid segmental excisionseoncentric with the ports and of greatercircumierenee than same,

so as to form a seat for the valve formed by the central part of thesaid segment. To the bottom of the cylinders is fitted an air-tight caseor chamber, d, formed of two horizontal sections, the upper of-which issecured to the cylinders by a rod, r, at opposite sides of thecylinders, connected with a lug on the cap 0, and passing through alug-on the chamber d, and provided with a nut on the under side of thelatter. The lower section of the chamber 61 is attached to the uppersection of same by bolts passing through lugs on the respective parts.To the bottom of the lower section is connected the suction-pipe e, andthe two cylinders A A are made to communicate with this pipe, separatelyand independent of each other, by a horizontal diaphragm, f, near thebottom of the chamber d, and a vertical partition, g, extends from saiddiaphragm to the cylinders,

I the diaphragmf being provided with a valve for each cylinder.

In bearings cast on the adjacent edges of the two sections of thechamber at is fitted a horizontal crank-shaft, it, having under eachcylinder a crank standing in opposite direction from the other. To thecranks are connected rods '5, which extend into the cylinders and arehinged or pivoted to a plunger, 7c,'whieh is provided with a valve andmaintained in. proper horizontal position by guides I extendin g fromits sides and fitted to slide on the interior of the cylinders. One endof the crankshaft protrudes through the chamber 4, and is provided atthe outside thereof with a miterpinion, m, into which meshesamiter-gear, n, fixed on the lower extremity of a rod, 0, which passesthrough bearings in lugs 19 and p, respectively, on the chamber cZ-andcap 0, and is extended to the top of the well or locality where the pumpis to be operated.

The upper extremity of the rod 0 passes through the cap-piece of astandard, q, and is provided above same withabevel-gear, s, which isengaged by a bevel-gear wheel, 8, mounted on a shaft, to which a crank,w, is connected. In order to protect the said gears from ice and frombeing tampered with, and also to guard against accident from collisionwith same, the gears are inclosed in a case formed of two concavecircular plates, 1? t, joined with each other by peripheral flanges ontheir respective concave sides. The plate 15 is firmly attached to thestandard q, and the plate t is secured to the fixed plate by thecrank-shaft passing through the two plates and having a head on one endand the hand-crank upon the opposite end. From the standard (1 isextended a horizontal arm, a, the free end of which is provided with an'orifice, through which the discharge-pipe passes, and by means of aset-screw, o, the arm is clamped to the said pipe, and thus both thestandard and pipe braoedin a simple and efi'ectual manner.

With pumps designed for localities where they are exposed to sand andgrit, I incase the lower gears, m and a, as indicated by dotted lines inFig. 2 of the drawing; and in case the pump is to be partly or whollysubmerged, I dispense with the lower section of the ohan1- ber 11 andsubstitute therefor a plate, 1, secured to the upper section of thechamber at in the same manner.

The pump is supported by means of a post driven in the bottom of thewell, and having secured to its top a cap which has arms extended to thelugs on the plate 1, and is connected thereto by the bolt which securesthe said plate to the chamber d, as illustrated in Fig. 4 of thedrawing.

Havingdescribed my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. The combination, with the cylinders A A, having on top the plate a,provided with valves, and the cap 0, mounted on top of said plate, ofthe chamber d, provided with suction-pipe a, horizontal diaphragm f, andpartition g, the crank-shaft h, rods 43 t, and plungers 70 k, providedwith valves, all constructed and arranged substantially in the mannerdescribed and shown.

2. In combination with the cylinders A A, crank-shaft h, and rod 0, thecap 0, provided with lug p, and the chamber d, provided with lugp,substantially as specified and shown.

3. The combination of the cylinders A A, cap a, rod r, chamber (1,divided horizontally at the axial center of the crank-shaft h, andprovided on their respective adjacent edges with bearings for the'saidshaft, all constructed and combined substantially as described andshown.

4. In combination with the rod' 0, provided with pinion s, the standardq, provided with case t t, the gear-wheel s, mounted on a shaft extendedthrough the said case, and the crank w, all substantially as specifiedand shown.

5. In combination with the rod 0, gears s s, and discharge-pipe, thestandard q, provided with the case it t and the arm u, and set-screw 17,substantially in the manner described and shown, for the purpose setforth.

In testimony whereof I have hereunto set my hand this 9th day ofOctober, 1878.
